Memory Leak to an Unauthorized Actor vulnerability in Tobit Laboratories AG TeamDavid's Webbox allows reading of sensitive information. When accessing the URL “/.well-known/mta-sts.”, the application responds with memory. By repeatedly requesting this endpoint, an attacker can access sensitive information, including user passwords. Exploitation does not require authentication. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
